I installed a plugin on my website and now it's causing all my backend pages to be blocked and show a white screen. I can view the website fine but the dashboard, themes, etc. is all white screens. I did try and log out and log back in and now I can't even get to the login page. Any help would be greatly appreciated!

Yes, I contacted my host provider and they suggested disabling the plugin. And they also increased my memory limit. So now I can view all areas on the backend. So it's all fixed, I appreciate your help though.
